WatchOS 7.5 battery drain

Anyone else having a horrible battery life on the latest watch update? I have the series 5 on watch OS 7.5. Since the update my watch won’t make it 16 hours.

Before the update, I would be able to go to bed with my watch at 100%, use it for sleep mode and wake up alarm. Exercise in the morning for 30 minutes and go on my day. At night I would still have 20-30% battery before charging it.

Doing the same routine, 2 days in a row my watch doesn't make it past lunch. I do not use the always on display function either.

Last night I reset my watch and restored from backup. Charged to 100%, went to bed wearing it, woke up this morning to 70%.

Hope a new update comes fast or wearing the watch is pointless with this terrible battery drain.

I’ve had the same issue.

After a week trying different routes, I’ve found what has worked and that is turning off the environmental sound measurements functionality in Privacy at least until Apple fixes the bug.

It looks like the functionality is running constantly in the back taking too much power, since the battery drains at a constant pace.

Hope it helps others!

I just checked and mine has been turned off this whole time and I still have fast battery drainage since the last update. I think it is just the update. Something in the code is causing the battery to drain fast. They just need to fix and send out another update. 😫

Turning off "Background App Refresh" helped (a lot, I think):

In the Watch App (on your iPhone) -> General -> Background App Refresh -> turn off "Background App Refresh"

This was one of many suggestions during a visit to the "Genius Bar" (or whatever they are calling it).

After turning "background app refresh" off I haven't noticed any loss of function on the watch.

I have Apple Watch series 6 and now the 7.6 update and my watch did great with all the other updates but now 7.6 is draining my battery. I tried reloading it, restarting it, delete unused apps and still charging 2-3 times per day and I mainly use it as a watch. Makes me sad :(

I have the most recent update, my battery health is 100%, and after 9 hours of not even really using it (cellular on, but I haven't used it to track a workout, listen to music, use any apps, etc), it's already down to 27%. I updated the OS last night. I've only had the watch for a few months, and it's a Series 6.

On update 7.6.1, my watch is a lot better with battery life. Nothing like before 7.5 update. However, I am able to go to sleep with a full charge, use it for sleep mode and wear it all day the next day and get in a 30 minute workout with battery life left before charging it again the next night. Hopefully all other watches out there with issues start stabilizing. If not then hopefully the next major update fixes the battery issue.

Can’t say that 7.6.1 did anything to improve the dramatic use of battery since 7.5.

i’m retired and not running marathons or working out for hours.

Prior to 7.5 I could put my watch on the charger every morning at about the same time with 25%+ left on the battery.

Now if I’m lucky to be in the red zone with 10%-.

Nothing has changed with the most recent iOS or watchOS updates, I’m still left with a watch performing at a significant loss in functionality.

I advised my 84 year old brother, who recently lost his older Apple Watch to hold off buying a new one until all this tohubohu (word of the day) dies down.

Check your battery health here;

At 80% it is recommended that you replace the battery.

Ok.

I powered off the watch and started again, now the backup is normal, same as before. No rapid reduction in battery in same level of usage.

But if you turn off Bluetooth can you connect your watch to your phone? Using Bluetooth from phone saves a lot of battery.

In addition to this, my battery health has gone to 88% from 93% in 3 months, which is related to the extra charging during the day :(

Thank you Apple.
